This invention relates to agricultural implements and its general object is to provide an attachment for a plow in the form of a subsoiler that is adjustable to vary the height thereof with respect to the ground, in an easy 5 and expeditious manner and while the plow is in motion if desired.

Another object of the invention is to provide a subsoiler that can be attached to plow beams of various diameters and with very little effort.

A still further object of the invention is to provide a subsoiler of the character set forth, that includes a root cutter mounted for cooperation with the plow of the subsoiler,

Another object of the invention is tov provide asubsoiler that is simple in construction, inexpensive to manufacture, and extremely efficient in operation and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawingv and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure lis a side elevation of the subsoiler which forms the subject matter of the present invention and illustrates the same attached to a plow.

Figure 6 is a sectional view taken approximately on line 6--6 of Figure 1, looking in the direction of the arrows.

Figure 7 is a sectional viewtaken approximately on line 7-7 of Figure l, looking in the direction of thearrows.

Referring to the drawing in detail, the' letter A indicates the beam of a plow which is of the usual construction, and the attachment which forms the subject matter of the present invention is secured to the beam as clearly shown in Figure 1. y

The attachment which in fact is a subsoiler as has been previouslyr set forth includes a beam 1 that is curved upon itself to provide a vertical portion 2, the latter being hollow for the major portion of its length as at 3, and this hollow portion is provided with an opening arranged in the rear thereof as best shown in Figure 2.

The end of the beam l opposite to the hollow portion is pivotally secured to a clamping means which is adapted to secure the subsoiler to the beam A, and this clamping means includes a strip 4 having one end arranged at right angles with respect to the body portion. The right angle bentend of the strip 4 is provided with 'a threaded opening while the body portion is likewise` provided with a threaded opening, the latter being indicated by the reference numeral 5, and the body portion is valsov provided with an opening 6 that is adapted to register with an opening 7 arranged through the reinforced or enlarged end of l'a companion strip 8 that is likewise provided with a right angle bent end 9 which is ser- Y rated as shown. Arranged at the right `angle '8e bent end 9 vis a slot adaptedto register with the opening of the right angle bent end of the strip 4 and a serrated block 10 cooperates with the right angle bent end 9 for the purpose of receiving a bolt 11 that isl provided with a lock nut 12, the bolt 11 being adapted` to engage the beam A when the arts are associated therewith as shown in figure ,4, and passing through the openings 6 and 7 is a bolt and nut connection 13 which 'pivotally secures the beam 1 with respect to the beam A. A bracing member 14 has one end secured to the bolt of the bolt and nut connection 13 and this last mentioned end is provided with an opening through'which passes '10U l cooperation with the bolt 11.

The opposite end of the bracing member 14 is secured to the ears 16 of a collar 17, the latter surrounding the lower end of the hollow portion of the beam 1 as best shown in Figure 2. Y v

. Extending from the beam 1 at the top of the vertical portion thereof is an apertured lug 18 that has pivotally secured thereto the enlarged lower end of an operating member 19 and this operating member includes a shank from which extends a pin 2O arranged in a slot 21 of a handle 22 that has. secured thereto a collar 23 for the purpose of receiving the shank as shown in Figure 1. By this construction, it will be apparent that when it is not desired to use the handle, it canA be moved to either of its dotted line positions as shown in Figure l, but when the handle is to be used in a manner which will bepresentl'ly described,.it is arranged in its full line position in Figure l.,

The enlarged portion .ofr the operating member 19 has pivotally secured thereto one ofthe ends Yof a link24, while the opposite end of said link 24 is pivotally secured to a tongue 25 -that is formed with the shank 26 of the plow bracket A27 for the plow of the subsoiler. y v

Extending from the beam 1 is a stud 28 that is adapted to be received in any one of anumber ofnotches 29 which are formed with the verticalportion of a latching member 30 which is also pivotally secured to the tongue 25 as best shown in Figure 6 and the latching member 30 has extending therefrom a lever 31 for the purpose of receiving the footof the operator of the device. Extending from the bolt and nut connection 13 is an eyed link member 32, while extending from the latching member 30 is a similar eyed link member 33, and these eyed link members 32 and 33 have secured thereto the ends of a coil spring 34 whichis adapted to hold one of the notches of the operating member 30 with the stud 28 disposed therein as shown inFigure 1. r

The plow of the subsoiler is preferably formed from a single piece of material and the mold board portion thereof which isindicated by the reference numeral 35 is curved transversely upon itself as best shown in Figure 2, andthe landside portion of the subsoiler plow has fixed thereto the plow bracket 27'which is provided with a pair of slots and an opening, the latter being adapted to receive a bolt4 and nut connection 36 whereby the plow is pivotally associated with the bracket 27 and adjustable thereon through the medium yof bolt and nut connections 37 passing through the slots of the bracket.

ment of a Vwedge 38 thatis received between the upper end of the mold lboard and an angle bracket 39 formed with the shank 26.

A root cutting blade l0 has one of its ends i pin 4:1 which is attached to the shank 26 and Y extends through va slot formed in the hollow portion ofthe beam 1 as best shownV in Figure 2. The root cutter blade is provided with a sharpening forward edge.

"From the above description and disclosure of the drawing, it will be obvious that I have provided a subsoiler that can be easily and expeditiously attached to plow beams of various diameters and the height of the plow of the subsoilernis adjustable vertically. I*When it is desired to move the plowof the subsoiler the latohing member 30 is released from its stud 28, and the handle 22 has arranged in its full line position as shown in Figure 1 whereby it will act upon the operating member 19 for raising and lowering the plow as desired. The latching member 30 can be actuated vby the foot of the operator, and the plow of the subsoiler can vbe adjusted during movement of the plow if such action is necessary or desired.V

It is thought from the foregoing descripion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims. j
